Continuing a long-time station tradition, WCWP celebrates LIU Post Homecoming Weekend with alumni returning to host shows they did as students. Many favorites from the station’s history will join in the fun from Friday at noon through Sunday at midnight. While “The Grooveyard” will be not be heard this week as a result, host Alan Seltzer will bring back “Seltzer With a Twist” at a special time Friday night from 6-8 PM.
